Title: Door closing mechanism with damper - has internal stops for ensuring damping under action of external forces
Inventor: SITTMANN GEB VOESTER BRIGITTE
IPC: E05D7/08
Filed: 1974-08-01
Abstract: The closing mechanism for a door is fitted into a door. This mechanism has a housing for the closer rod and a slide with projections in contact with the rod. The slide is connected to a piston rod enclosed by a helical spring which in turn is connected to a damper cylinder. The end of the closing rod projecting from the housing is pivoted on a fixed bearing. A compact configuration is achieved because the internal connecting projections act as stops. Hence excessive external forces are not able to slam the door. The housing (1) has a bulge (2) in the region of the closing mechanism pivot to ensure relative movement for the cams and the slide (45). This slide comes into contact with guide lugs for actuating the damping piston.

Title: Textured areas prodn. method for photographic copier - first exposure transfers black and white contrast and second exposure transfers texture from standard sheets
Inventor: SIEBERS HEINRICH
IPC: G03C5/08
Filed: 1975-07-02
Abstract: The photographic copying process avoids the monotonous labour of drawing in a standard texture-hatching, repeated decorative motif, or the like. Instead, a single standard sheet, covered all over with the required texture, is associated with a series of originals of each of which the relevant areas are defined in black and white contrast only. The first exposure transfers the black and white contrast from the original to the light-sensitive paper, where it becomes an exposed-unexposed contrast. A second exposure transfers the texture from the standard sheet to the entire copy, but effectively only to the area still remaining unexposed. The copy is then ready for developing.

Title: Aiding removal of moisture from monolithic furnace linings when fritti - by incorporating hemp ropes which act as capillary channels
Inventor: FRICKE HEINZ DIPL ING
IPC: F27B7/28
Filed: 1975-09-20
Abstract: The network of hemp rope is secured to the shell of the furnace and the monolithic refractory is then cast in place perforated by channels running radially from the shell to the inside of the furnace. These channels are associated with the rope network. When the furnace warmed up initially the hemp ropes suck up moisture uniformly from the refractory as it dries out and this water passes out through the perforated channels into the furnace interior. When the normal operating temperature is reached the ropes and their cement burn away without residue leaving a further series of channels in the refractory. Used in industrial ovens and furnaces which have cast or formed refractory linings requiring to be dewatered before initial use. Provides uniform removal of water from the refractory allowing rapid initial heating up before use.
